Improvement in extension pruning-hooks



JOHN s-TARfIg, or THOMASVILLE, GEORGIA.' Letters Patent No. 87,719, dated Mwrch), 1869; antedatefl February 27, 1869.

IMPROVEMENT IN vExI'EN'sIoN IRIININce-HoOKsl The Schedule referred to in these Letters Patenti and making part of the same.

the county of Thomas, an` State of Georgia, have invented a new and useful improvement in Extension Pruning-Shears; and I do hereby declare that the following is a full, clear, and exact description thereof,

which will enable -those skilled in the art to make and use the saine, reference being had tothe aceolnpanying drawings, forming part oi' this specification.

This improvement relates to lever-shears for pruning fruit and other trees, whereby the shears may be eX- tended -,so as to be 4used as either hand 'or pole-shears; and e Y It consists in shaping and arranging the cuttingedges of the shears sothat the cutting of the branch commences at the top side, thus greatly facilitating the operation of pruning; and also in the arrangeinent of the parts whereby the shears are inade convertible from pole to hand-shears, as will be hereinafter more lfully described.

The drawing- Figure ln'epresents a longitudinal view of the shears, extended as when used as pole-shears, or for reaching the higher branches. t

Figure 2 represents the shears as when used for hand-shears, for light pruning.

Similar letters of reference indicate corresponding parts. i

A is' the pole, which is made. so as to be extended, as seen at the sleeve-coupling B.

C is a level', which has its fulcrum on the pole at d,

'and which is connected with the lever-end of the movable knife E by the rod F.

The movable cutting-knife E is a lever, which ha its fulerum at g, as seen in the drawing.

The shear-blade 71l is fastened to the pole A.

As represented in the drawing, the poleis extended, and a handle, I, is attached to the lever O, for operating the shears by the power of the foot with acornpoundlever purchase.

To change the shears so as to adapt them to handuse, the shear-blade lt is removed from the top of the pole, and insertedl into the part of the polelmarked J,

. or intoa separate handle.

When thus used, the rod F is dispensed with, and

the power is applied by the Ahand to the handle L of the lever C.

This lever7 0and the lever of the movable knife E, are bolted together, as seen in iig. 2, the two levers, in this instance, forming but a single lever, and consequently operating with less power, but still as powerfully as the ordinary pruning-shears, and sufficiently so for light pruning.

`I claim as new, and desire to seeure by Letters Patent-.-

The shearfblade h,andthe movable cutter E, eonstrneted arranged, and operating substantially as shown and described, for the purposes set forth. n
